Abstract

In the present paper we investigate scattering of low and intermediate degree p‐modes on a thin magnetic fluxtube embedded into a stratified polytropic atmosphere. Using the Born approximation approach we find the solution of linearized MHD equations and calculate resulting phase shifts of scattered waves for different sets of fluxtube parameters. Possible application of the results to the analysis of observational data is discussed. (Β© 2007 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

We show that up to second order in the thinness parameter, the equations of equilibrium of a thin, isolated, axisymmetrie, force-free magnetic flux tube in a stratified atmosphere and the other essential constraints form a mathematically closed system. Auxiliary assumptions about temperature of the
